Sanitization Process

MethodNVMe Firmware Purge (Sanitize / Format)
Compliance standardNIST SP 800-88 Rev. 1 - Purge
Sanitization categoryPURGE (NIST SP 800-88 Rev. 1) - firmware sanitize
Standards referenceNIST SP 800-88 Rev. 1 - Purge (firmware sanitize, NVMe Sanitize / Format NVM). Consistent with CSE ITSP.40.006. Purge addresses reallocated and over-provisioned areas that overwriting (Clear) cannot reach.
Firmware commandNVMe Sanitize block erase: physical erase, reads zero, covers the whole medium including over-provisioned/spare (NIST 800-88 Purge)

Media advisoryThis device is solid-state media. Overwriting achieves NIST SP 800-88 Rev. 1 CLEAR, not PURGE: wear-leveled and overprovisioned areas of flash media are not addressed by overwrites. For PURGE, use firmware-level sanitization (ATA SECURE ERASE / NVMe Sanitize).

Verification

Final readable stateCONFIRMED 0x00 (zeros): read-back at 100% (full read-back) sampled 8 of 8 region(s) - the first and last always included - and found only zero bytes.
Excluded from the state above (bad sectors)None - every readable sampled region is covered by the state above.
MethodAdvisory spot check - post-sanitize read-back sampling (evidence of sanitization; NOT the verification)
FindingAll 16 spot-check regions read as constant 0x00, consistent with a block erase.
Spot-check regions16
Unreadable regions0
NoteFor a firmware Purge no known pattern is written, so this spot check records evidence of sanitization rather than a byte-for-byte pattern comparison. The authoritative result is the 'Final readable state' row, produced by the full verification read-back - its region count comes from that separate, larger sampling.

Exceptions

Skipped bad sectorsNone
